Switch "docker-compose" to "docker compose".

[felddy]

💡 Summary

The docker command is now capable of doing the work of docker-compose. This message is now emitted by docker-compose:

❱ docker-compose up
Docker Compose is now in the Docker CLI, try `docker compose up`

Motivation and context

Eventually this will be the way™.

Implementation notes

https://docs.docker.com/compose/cli-command/

I've noticed that the new command is more pedantic about the docker-compose.yml files.
Specifically, it does not permit quoted integers for port numbers.

Acceptance criteria

How do we know when this work is done?

• all docker-compose references converted to docker compose
• all included docker-compose.yml files work with new command

Greetings,
I have no clue what skeleton-docker is, but having stumbled on this ticket, I would advise you to have a look at the ticket about compose-cli's new message, which indicates that docker compose up in currently in preview, before proceeding with this.

This appears to have been done in #105.
